Question:
how to move a float value to a register like xmm# or mm#?(mov xmm0,(float/double)# not working)
also,Is there any good tutorial about how to make a custom scan that does a known operation (adds n number to every value or multiplies/divides any value by n' number or scan for (un)Xored values in a game like chicken invaders (encrypted values))?thanks.
Bugs:
1-[MAJOR BUG]:In both float and double (floating points),when you first make an "unknown initial value" scan,the "increased/decreased value by x amount isn't working,try opening ce,choosing a random process,scanning for "Unknown I.V." and using increased/decreased value by a big amount (like 546910634) and do many similar rescans,you'll notice the bug.
2-[MINOR]Open new scan tab/(Choose any scan type (integer or floating point),do unknown initial value) on both,when you'll go to the other one,you'll find 0 results.
3-[MINOR]Place a cheat table inside a folder and use unicode characters to rename the folder (like ☺☻♥♦♣♠•◘○◙♪♫☼►◄↕‼ etc.),then try to open the cheat table and it won't work (It'll just open a blank CE window).
4-[MINOR]Spellar mistake in the auto assembler:"you havn't specified a DISABLE section",It should be "haven't"
5-[MINOR]If you open a file in cheat engine (process/open file),then scan for a value and "find out what writes/accesses it" (attach debugger),your PC will crash,I know it's stupid but the option shouldn't be there.
5-[MINOR]If you open a file in cheat engine (process/open file),then scan for unknown initial value you'll have n results,if you do a rescan with "unchanged" option it'll show n-3 results,otherwise,if you scan for "changed" values after the initial scan you'll have 0 results,that means that the results counter is doing something wrong.
Suggestion:
1-[IMPORTANT]A changed/unchanged rescan option for string values,especially useful in games like z-rox where you must type the answer of every level,to find the address that holds the correct answer.
2-[LESS IMPORTANT]Syntax for float registers:In the ASM,the synax highlightning makes it much easier to detect mistakes and stuff like that,while the normal registers have an orange color (eax,ebx,esp,ebp,esi,edi etc.),the float registers (like xmm0,xmm1,mm0,mm1) are not highlightened.
3-[AVERAGE]An option to scan for "static addresses only" (green),just put a checkbox under the scan :
|Checked: Scan only static addresses.
|Unckecked: Don't scan static addresses.
|Gray:Don't care if it's static or not.
|With the setting : Gray by defaut.

@Dark-byte: Good luck Improving CE,I hope that you'll use this topic to make your amazing software even better.
Also,I'm using Cheat engine 6.3 no_setup.
Windows XP.

I'll check it out
About suggestion 4, is it a .exe, .ct or something else you launched?

@Redone, it's perfectly normal.

You can not open other files like this:

@Redone
No, you do not understand.

I'll check them out when i get time (dq has already been fixed, and the mm* registers will be fixed too)

As for 1, those results seem correct. Floating point values are not precise values.
14E44 + 100000 = 14E44

I can't add a scan to see if it's different first, because increased value by 0 is a valid option as well, especially for floats


And I'm not sure the changed/unchanged string values is as usable as you might think. Most programming languages allocate a whole new memory block whenever a string get changed

Anything specific you do when you get the debugger crash? (Which debugger interface? What type of breakpoints? How many breakpoints where active? Did you use the tracer? Where you manually tracing ? Did you have a lua script that intercepts debug events running? )
